Specifications, Pricing and Availability
Plextor released the M5 Pro in three capacity sizes - 128GB, 256GB and a large 512GB. Along with the NAND capacity, the DRAM volume scaled with the capacity size. The 128GB model we're looking at today uses a single 256MB DDR DRAM chip for holding page data.
The performance scales as well as the capacity size increases. The 128GB model we're looking at today delivers 540MB/s sequential read and 330MB/s sequential write speeds. Claimed 4K IOPS read is 92K while 4K IOPS write is 82K.
Plextor built the M5 Pro in a 7mm z-height so the drives will work in new ultrabooks that don't have enough space for 9.5mm drives.
Plextor covers their M5 Pro with a five year warranty and also includes a nice accessory package. Echo, Backup Now EZ and SSD Performance Analyzer are included and well as trial software. On the hardware side, Plextor includes a desktop adapter bracket and screws for easy desktop installation.
There are a handful of Plextor M5 Pro drives still out there according to Google Shopping. Plextor replaced this model with the new M5 Pro Xtreme, but that means you can find a few of these on sale. On Google Shopping we found the M5 Pro for as low as $130, but at the same time we found the M5 Pro Xtreme for $123.99. At some point the remaining M5 Pro drives with 8K page sizes may dip below the price of the Xtreme models to get them out of the warehouse. That's what we're hoping for anyhow.
